In this contemporary version of Hawaii Five-0, a new elite federalized task force is formed with a mission to tackle crime in the Aloha State. Detective Steve McGarrett, a decorated US Navy lieutenant commander turned cop, returns to Oahu to investigate his father's murder and stays after Hawaii's governor persuades him to head up the new team: his rules, her backing, no red tape and full blanket immunity to hunt down the biggest "game" in town. Joining McGarrett is Detective Danny "Danno" Williams, a newly relocated ex-New Jersey cop who prefers skyscrapers to the coastline but is committed to keeping the Islands safe for his 8-year-old daughter (His re-married ex-wife also lives in Honolulu); and Chin Ho Kelly, an ex-Honolulu Police detective wrongly accused of corruption and relegated to a federal security patrol, who is also a former protege of McGarrett's father. Chin's cousin, Kono, is a beautiful and fearless local, fresh out of the academy and eager to establish herself among the department's elite. McGarrett vows to bring closure to his father's case while the state's brash new FIVE-0 unit, who may spar and jest among themselves, is determined to eliminate the seedy elements from the 50th state.
